The Adapt is hands down, the only shoe I have ever felt good lifting in. The zero drop and flexible sole make me feel like I'm training barefoot while simultaneously feeling protected and able to handle higher impact training. I've never found that in a shoe before.

I have literally tried every lifting/ fitness shoe on the market. The adapt trainer is a game changer for me because of the flexibility, comfort, and the fact that they look so cool. I have ran, lifted, and jumped in them. They check all the boxes.

I especially love the adapt shoes because they allow for great stability having a flat sole and and wide toe box. Not only that, but they are also comfortable, stylish, and super easy to slip on.

The Adapt Trainer is the modern minimalist shoe I've been waiting for. Perfect foot shape fit, stylish to wear beyond the gym/workout, and the fact that they clean so easily in the wash is icing on the cake.

I've hardly worn any other shoes since getting my first pair. Adapt trainers are crazy comfortable, super flexible, and surprisingly durable. They are my go-to everyday shoes and I genuinely highly recommend them.

    Good transition shoe

    Got these for my dad as a birthday gift last year and they seem to be holding up well! The first pair I ordered was definitely too small on him so I had to exchange them for a larger size. I still think they're a bit snug, but since he prefers a tighter fit for his narrow feet it's perfectly acceptable. The foot-shaped toe box definitely makes up for the lack of width., but it's probably worth sizing up a full size if you have smaller feet - he normally gets a size 5 or 6 and size 7 is still a tad snug in these, but the build quality and comfort seem to be serving him adequately. The cushion and lowkey design make them a great transition shoe, though the Adapt Runners are probably even better for that unless you need a lower stack height. Definitely recommended.

    New Favorite Shoes

    This brand and these trainers are my new favorites. Right off the bat, I typically wear an 8 in women, but the size recommendations are to size up—I contacted Flux and asked whether I should size up a half or a whole size, and they said half. I got an 8 & 1/2, and they fit perfectly. The outer material is very forgiving in fit and movement. They slide on easily. The inner massaging liner is what all shoes should have. The flat laces and holes for lacing are so innovative—they don’t get all twisted. The wide toe box and zero-drop sole I’ve read so much about have even changed my walk for the better when I remove the shoes. No more pointy-toed shoes for me! They are comfortable when walking, like I have nothing on my feet yet am supported. I love the Sand color that I got for everyday wear for work—they can get dirty because they are the color of dirt, and it’s no big deal! I’ve not had to wash them yet, but, when I do, I know that I can throw them in the washer—one of the reasons I bought this particular shoe. I also got the trainers in Whiteout for casual occasions—haven’t even gotten to wear those yet. If I could change some things about this shoe, and why I’m only giving this a 4-star rating versus a 5, I would want just one side of the tongue of the shoe to be attached/sewn to the shoe—my foot is narrow but arched, so I always have to adjust the tongue back to midline; having one side attached/sewn would allow for donning and doffing the shoe but would also keep the…

    Not good for barefoot or no-show socks

    I wore these for about 5 minutes before the side under the ankle bone started rubbing my skin off. That said, they are very flexible and flat and otherwise seemed comfortable. I just need to wear only higher socks with them, which I hate. They were all final sale at the time of my purchase which also put me in a weird spot to commit before I knew this. Obviously everyone has different foot dimensions, but all of this made it a 3-star experience for me.

    As a teacher, it is hard to find comfortable shoes that do not hurt my feet. The adapt trainers are the best for always walking around. They help keep my feet comfortable and I have enough room in my toe box to move my toes! You won’t be disappointed! When buying them make sure you size up because they ran small. Even when I sized up they are not too big, they fit well!

Wearing bulky shoes is like keeping your feet in casts. Sure, they’re temporarily safe, and may even be able to recover from overuse, but this is merely a band-aid, not a long term solution. Your body works and feels best when it’s being used and appropriately challenged.

  • Stronger Feet: Traditional shoes restrict movement and weaken foot muscles over time. Barefoot shoes promote natural movement, strengthening muscles in the feet, ankles, and lower legs for better stability and strength.
  • Happier Toes: A wide toe-box gives your toes freedom to wiggle and flex. This builds up their strength and flexibility, making it easier to move around without hurting your ankles or knees.
  • Balanced Stride: A zero-drop design, meaning your heel and forefoot are on the same level, gives you a natural, graceful stride that takes the strain off your joints and perks up your posture.

"Barefoot shoes" is a general term for shoes that optimize the natural biomechanics of the human foot. To achieve that, our shoes feature excellent flexibility, zero-drop (no heel raise), and a generous toe-box to accomodate the foot's natural shape.

Flux shoes have a generous toe-box, thanks to the toe-off shape which creates ample room for the toes throughout the gait cycle.

Yes, these shoes are flat from heel to toe, allowing your feet to land naturally.

The amount of time it takes to transition to barefoot shoes varies for each individual, as everyone's feet are different and may adapt to the new shoes at different rates. However, the following general guidelines can help:

  • Gradual transition: Gradually increasing the amount of time you spend in barefoot shoes can help reduce discomfort and allow your feet to adjust to the new sensation of walking without shoes.
  • Start small: Begin by wearing barefoot shoes for a few hours at a time and gradually increase the duration as your feet get used to them.
  • Listen to your body: Pay attention to any discomfort or pain you experience while wearing barefoot shoes. If you experience discomfort, take a break and switch back to your regular shoes for a few days.
  • Give it time: It can take several weeks or even months for your feet to fully adjust to barefoot shoes, so be patient and persistent.

Keep in mind that everyone's feet are different and the transition time may vary. It's important to listen to your body and adjust accordingly to ensure a comfortable transition to barefoot shoes.
